Wilms tumor is a cancer of the kidney. The epidemiology, presentation, diagnosis, and staging of Wilms tumor are discussed separately. The prognosis of adults with WT is poor compared with children who have a 85% chance of cure. Radiotherapy to the abdomen and chest wall as well as chemotherapy in the form of actinomycin D, vincristine, and cyclophosphamide was given. Wilms tumor is typically found in children younger than five years old. Five-year overall survival (OS) rates have dramatically improved with multimodal therapy and now approach 90 percent. Historically in the 1980's, most series of adult cases had reported long-term survival of about 25%. The 5-year survival rate in case of children suffering from Wilms Tumor is about 93 percent. Wilms tumor can develop in one or both kidneys. Wilms' tumor is not confined to children and it can also involve older children and even adults. [1] [2] It is also the most common pediatric abdominal cancer and the fourth most common pediatric cancer overall.
